Struct SweepLoop 

pub struct SweepLoop {
    pub profile: Profile,
    pub poles: Vec<bool>,
    pub on_axis: Vec<bool>,
    pub apex: bool,
}

One profile loop or chain to sweep, and which of its joints are poles and which of its curves lie on the axis (see the module docs). A curve on the axis runs between two poles.

Fields

profile: Profile

poles: Vec<bool>

Per joint: whether it lies on the axis.

on_axis: Vec<bool>

Per curve: whether it lies along the axis.

apex: bool

Whether the loop is collapsed to one point, every curve degenerate there: the apex a loft to a point comes to (see [skin]).

Implementations

impl SweepLoop

pub fn plain(profile: Profile) -> Self

profile, clear of any axis.

pub fn reversed(&self) -> Self

The same loop traversed the other way; every flag stays with its curve or joint (see Profile::reversed).

pub fn at_corners(&self) -> GeopResult<Self>

The same loop with every curve cut at its corners: the knots inside it where the curve is only C0 and turns, its tangent coming in definitely not along the one going out — a polyline given as one curve, a curve a STEP file gives with a kink. Swept whole, such a curve makes a wall creased inside one face, which every question about a face’s normal — an offset, a blend, a silhouette — takes for one smooth surface. Cut, the crease is an edge. The pieces of a curve X are X, X#k1, X#k2, …, the joints between them X@k1, X@k2, …; each piece is an exact piece of the curve, on [0, 1]. A joint inside a curve on the axis is a pole.
